Extreme unproffesional staff

I was referred to Henrico Jacobs who wanted a quotation from me. I tried to call Henrico three times over 2 days. He eventually called me and I gave him a quotation. Then he disappeared. He then ignored me for days. I called him several times and sent messages to him. He did not answer any of these. Out of the blue weeks later he contacted me on WhatsApp and asked another question. I answered him and then he disappeared again. He then messaged me again asking questions, I tried to contact him again but he never answered me, or contacted me back. I then sent him a message I finally realised that he was wasting my time and I then sent him a message telling him that I am withdrawing all quotations that I had sent to him. I think this is extremely unprofessional behaviour and I will never do business with this company if this is their standard of working with suppliers.
